CHUBN-OPERATING DEVICE.

Specification of Letters Patent.

Patented June 21, 1921.

Application filed July 2, 1920. Serial No. 393,532.

T 0 all whom it may concern Be it known that I, HENRY POAGE, a citizen of the United States, residing at Mill Point, in the county of Pocahontas and State of West Virginia, have invented certain new and useful Improvements in Churn- Operating Devices, of which the followlng is a specification. I

This invention relates to churn operating devices, adapted particularly for use in connection with barrel churns, and has for its primary object to provide mechanism of simple construction for greatly simplifying the churning operation and minimizing the amount of effort required for the operation of such devices.

A further object of the invention is to provide a machine of such character that barrel churns of the type now generally known and in use may be quickly and easily applied to the machine to be operated thereby, and which require no changing or modification of parts to enable them to be operatively held and operated by the machine.

A further object is the provision of means on a machine of the character described whereby churns varying in size may be applied to and operated by. the dasher operating mechanism.

A further object is to provide a machine of the character. stated which has its parts so arranged and located upon the support ing frame, and which accommodates the churn in such manner that the device is evenly balanced, whereby danger of the machine being overturned is obviated, and whereby the weight, and strains due to the operation of the machine are evenly distributed to all parts of the supporting structure.

A still further object of the invention is the provision of a machine of the character and for the purposes stated which is featured by means of an improved nature for detachably holding the dasher rod to the operating arm of the mechanism.

With these objects in view, together with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the clalm.

In the draw1ngsz- Figure 1, is a side elevation of a churn operating achine constructed in accordance with my invention, the machine being shown with a conventional form of barrel churn applied thereto,

Fig. 2, is an end view of the improved machine, and

F 3, is a top plan view of the machine.

Generally stated, the invention consists in a supporting structure constituting a frame of light construction which can be moved about easily and without much effort, and upon the lower part of which a suitable rest or platform is arranged for the reception of the churn. The operating mechanism is arranged upon the frame at the upper part thereof, and consists mainly of a rock arm to be attached to the upper end of the churn dasher rod, a support for the rock arm,

means in connection with said arm and support whereby the arm may be made adaptable to churns of various sizes, a crank, means for manually operating the crank with a minimum amount of exertion, and a connection between the crank and the rock arm. Furthermore, the rock arm overlies the churn holding platform in such manner that the dasher rod and arm are properly centered, whereby the connecting operation is facilitated, regardless of the size or type of churn applied to the machine. The attachment of the dasher rod to the rock arm is accomplished by means of a spring pressed pin; the latter being secured to the arm so as to prevent loss of the same, and this spring at all times exerts pressure upon the pin so as to hold the latter securely in place.

More particularly, the frame comprises uprights indicated at 4;, arranged apart in proper spaced relation, connected together at their upper ends by longitudinal bars 5 and transverse bars or beams 6. The end posts or uprights are connected near their lower ends by the transverse bars 7 the lat ter constituting supports for the platform 8 upon one end of which the churn 9 rests. The platform may be provided with blocks or cleats 10 to hold the churn in proper position on the platform, and one of these cleats (or both) may be made adjustable so that churn barrels of various sizes may be accommodated. To this end, the outer cleat, indicated at 11, is provided with spaced apertures for the reception of bolts 12, the bolts extending downwardly through the slots 13 arranged in spaced parallel relation in the platform. This construction permits of th cleat 11 being adjusted longitudinally of the platform and engaging the lower end of the churn, as will be under stood. It will be noted, furthermore, that the churn is disposed midway of the longitudinal edges of the platform, and the cleats maintain the churn in such position.

An upright or post 14 is arranged at the upper end or on top of the frame, and substantially midway the ends thereof. This upright, in'the present instance, comprises a pair of metallic strlps secured at their lower ends to the longltudmal bars of the frame and meeting over theilongitudinal center of whereby the throw of the rock arm may be varied The frame has arranged transversely thereof and near one end, a crank shatt- 18.

This shaft is arranged in suitable bezu'ings as vided with means shown, and has its crank 19 disposed above the longitudinal center of the pla form 8. This crank is connected, as by means ofthe link 20, with the adjacent 611(l0'lli316 rock arm 15, and it will be obvious that rotation of the crank shaft will cause the said sun to rock. A jack or'power shaft 21 is also journaled upon the upper end of the frame in suitable bearings, andhas secured thereto a gear 22, inmesh with the pinion 23 on the crank shaft 18. The power shaft, in the present instance, receives its rotation by operation of the crank or handle 2 T, but it will be understood that if desired this handle be replaced with a belt wheel or pulley so that the device may be coupled up wit. a source of mechanical power. The crank shaft has secured to outer end a balance or fly wheel 25, whereby the motion of the crank shaft will be steadied and the rotation made uniform.

The outer end 0' the rock arm 15 profor the attachment of same to the dasher T 26 of the churn. The

outer end of the arm is provided with'an op iing to receive the pin 27, the'latter .2

passing through an opening in the upper end of the dasher rod. In the oreseut instance the end of the rock arm is forked or bifur- 'cated, thus providing spaced arm portions to receive between them the end of the dashcr rod. The pin 27 is attached to the outer end of a flat spring 28, riveted or in any other preferred manner secured to the side of the rock arm inwardly from the outer end of the latter. This particular construction permits of the pin being easily and quickly applied to V or removed from the dasher rod, and the pin cannot become lost or misplaced he upper end of the dasher rod may be provided with a metallic plate 29, pivoted thereto as at 80, and the upper end of which is received between the furcations at the end of the rock arm. This arrangement, constitutinga link construction, obviates wear on the dasher rod and compensates for any inaccuracy in adjustment of the churn on the platform 8.

It will be noted that the power machinery androck arm are so arranged on the frame that the weightthereof is equally distributed to the supports of the frame, and that the combined weights of the churn and the machinery evenly balance the device so that the danger of overturning of the machine is overcome. Furthermore, the manner in which the mechanism is disposed upon the frame assures even motion during operation of the machinery.

From the-foregoing, it is obvious that I V have provided a machine for operating barrel churns which is of extremely simple construction, inexpensive tomanufacture, and which has its parts so constructed and assembled as to minimize the opportunity for wear, disorder or breakage. The machinery is so geared that it will be very easy to operate, andthe simplicity of the manner of connecting the rock arm to the dasher rod enables churns to be applied to or removed from the machine without the necessity of special skill or tools.

Ffhile the above is a description of the preferredembodiment of the invention,:it

will be understood that various changes in the minor details may be made without de-' parting from the spirit of the invention as defined by the claim.

I claim: r .ln a churn operating device, a frame including spaced paralleltop rails horizontally disposed, an inner rail between said top rails in the same plane and parallel with the latter, the said inner rail being closer to one of said top rails than theother, a gear shaft supported between said inner rail'ai'id the adjacent top rail, a gear on said shaft lying betweensaid inner and adjacent top rails, a crank shaft supported by'the said inner rail and the remote side rail, a pinion i on said crank shaft in the space between said inner rail and its adjacent top rail and in mesh wi h the said gear, a rock arm supported by said frame, a. link connectingsaid crank shaft with one endof said rock arm,

and means for connecting the other end of 'SEtlCl rock arm with a churn dasher.

In testimony whereof I ailiXiny signature.
